Someone help me...please!

We have just purchased Rational TestStudio having completed a successful evaluation period. The evaluation focussed upon Robot and met all of our pre-planned requirements so we went with it. The licence is now in place and it's time to start the planning proper...but where is a good starting point given the MASSES of documentation. Should it be setting up TestManager firstly and then creating automated tests using robot? Or should it be the other way around? Or should we start elsewhere. Any suggestions would be appreciated.
